I just tried DVDFab and it works really good, but it is incredibly slow. On a Quad core cpu machine with 8gb ram, velociraptors, and 50x DVD burnes, i get 3.5MB/s using HD Decryptor and it caps out around 6.5MB/s near halfway through. Anything I can do to speed this up? I noticed some people getting 14MB/s+ but I suspect I should be getting a lot better performance than this. It uses less than 1% cpu, I have run the program in parallel and used both DVD drives and both got the same speed, in succession, it is not saturation.

That 50x speed is for CD not DVD I do believe, and are your drives in DMA mode ?
